Mode Designation Error
Mitsubishi · FR-D700 Inverter (Basic)
What does Mode designation error mean?
Parameter setting has been attempted in External or NET operation mode when Pr. 77 Parameter write selection is not '2', or when the command source is not the operation panel. This error prevents parameter changes under specific operating mode constraints, aiming to maintain system stability and prevent unintended modifications.
Complete Troubleshooting Guide
- 1
Set the inverter's operation mode to 'PU operation mode' before attempting to set parameters from the panel.
- 2
Set '2' in Pr. 77 Parameter write selection to allow parameter writing in other operation modes (External/NET).
- 3
If the parameter unit (FR-PU04/FR-PU07) is disconnected, set Pr. 551 PU mode operation command source selection to '9999' (initial setting).
- 4
Alternatively, set Pr. 551 PU mode operation command source selection to '4' to designate the PU as the command source.
